METHOD OF PACKING ISINGLASS.

Specification of Letters Patent.

To all 1072 0122 it may concern:

Be it known that I, ARTHUR L. CANFIELD, a citizen of the United States, residing at Montclair, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Methods of Packing Isinglass, of wiich the following is a full, clear, and exact specification.

This invention relates to a method of packing isinglass, gelatin, or similar substances, and more particularly has reference to improvements whereby such material may be packed in more compact form tlan l eretofore and at the same time be more ell'ectually protected against deterioration and damage in transit.

Isinglass as it is technically know n-a form of gelatin is used in large quantities in the art of brewing, as ell as in numerous other arts, and is commonly prepared from fish sounds. This material is generally packed in wooden boxes for slipment to tie trade under more or less pressure; but t1 ere is considerable objection to ti is method of packing, since thei'naterial is bulky and also because it is frequently ruined by moisture, which causes it to swell and break tlc boxes. To prevent tl is, the boxes are in some in stances bound ith metal ioops; but tl is ex pedient is expensive, and, turti crmore, does not prevent t e material from being ruined by moisture. Such boxes are expensive, bulky, and cannot be made in an economical manner so as to witl stand damage in transit.

he objects of my invention are to provide an improved method of preparing tl is material for shipment whereby a greater quantity can be packed in a given space and at the same time reduce the chance of damage by moisture while in transit, as well as the cost of the packing-ca ses.

hese objects I accomplish by my invention, which consists generally in forming eylindrical coils of the isinglass, piling tlem edgewise one on another, and confining tliem under pressure in a moisture-proof containing-package which will not break by reason of the pressure and which will not require external securing devices. By my llfOtiUQi of preparing and slipping isinglass a large saving in bulk is secured, besides a stronger and lighter containing-package, and tlere ill be no loss because of damage by moisture or otherwise in transit.

The invention ill be more fully described in connection with tie accompanying drawings, which illustrate an embodiment of my invention.

l igure 1 represents a coil of tie material. Fig. 2 represents tle containing-package and tlc manner of compressing tl.e material tilOlCiD. Fig. 3 represents a commercial package, partly in section, containing isinglass prepared [or slipment according to my preferred method. Fig. 4 is a detail of a former used to lold ti 0 material.

1 represents a coil of isinglass or similar material before being packed, and 2 a metallic package or case composed of tie cylindrical or polygonal side 3 and a bottom 4, constructed to resist internal pressure. For

tl is purpose ti 0 side and bottom may be ilanged and interlocked, as SiiOWll, so as to form a strong joint and at tlie same time be easily rendered waterproof, as by soldering or ti o tigl tncss of tie joint itself.

TlIO coils l are preferably made of such diameter as to approximately fit witl in tl e cylindrical or polygonal case or package 2 and are packed tlerein by pressure. Because of ti e l'igh compressibility of tl is material it is desirable to compress as large a quantity as pcssiblc in one operation in order to save expense, and to tl is end a supplemental open-endcd former or jacket 5 is provided, wl ich is placed over tle case 2, as seen in Fig. 2, so as to contain a quantity of uncompressed coiled material additional to tl at wl'ich the case 2 w ill normally contain. Tl is former may be composed of hinged sections separably secured by a latch 6 and strengthened by outside loops 7.

S is a ram, operated by any suitable power, having a head 9, which may be made collapsible to facilitate withdrawal, as is well known in connection with mandrels and analogous devices. The case and former having been filled with coils overlying each other and preferably laid edgewise, pressure is applied by the ram to compress the material into the case 2 to the desired degree. The ram is then removed and more coils supplied, sullicient when compressed to fill the case, together with a flanged cover or lid 10, and the whole again compressed by the ram until the lid can be fastened by turning down the end of the case 2 beyond the beading 11. Additional fastenings, as rivets 12, may then be applied, and the cover may also be soldered if further security against moisture is desired. By releasing the latch 6 the former may be removed after the material has been pressed out of it without relieving the pressure of the ram on material within the case 2. The package is now ready for stock or shipment and may be kept indefinitely without danger of deterioration.

Such a package will withstand a much greater pressure from the contained material than can any wooden box even when bound with hoops, and inasmuch as the material will not be injured by any pressure which can be applied to it, besides being capable of a considerable degree of coiri iression, it follows that a very much greater quantity of material can be packed in a given space by my method of packing than has been possible with the known methods commonly used. There is new a considerable loss, due to moisture and other causes, such as destruction of the cases and spoiling of material in shipping isinglass, which will be entirely saved by my invention, and there will also be an additional saving in trar; portation charges, because a greater weight can be packed in a given space in a lighter ;t-acl'- age. Furthermore, the package itself is cheaper to manufacture. It will therefore be seen that with my improved method of packing compressible materials subject to deterioration by moisture, such isinglass, the objections and loss heretofore encountered will be avoided and the cases used will be less expensive and contain a greater quan tity of material.

The specific details of my invention may be modified according to the varying characteristics of the material to be pack d without departing from the scope of my invention, and I do not restrict myself to any particular material or construction of package.

Having thus described my inventic I declare that what I claim as new, and desire to secure by Letters Patent, is

1. The method of packing compressible sheet material, which consists in forming sheets into coils, compressing a plurality of such coils laid edgewise into a cylinder, anc closing said cylinder while holding the coils under pressn substantially as described.

2. The method of packing compressible sheet material into a cylinder, which consists in forming sheets into flat coils of greater diameter than thickness, compressing while supported against lateral displacement, a plurality of such. coils laid edgewise into said cylinder, and closing said cylinder after the coils have been compressed within its end, substantially as described.

The method of packing compressible sheet sheets into flat coils, laying plurality of said coils edgewise in a cylinder of substantially the diameter of said coils and having one end closed, compressing said coils and a cover into the cylinder by a ram, fastening said cover under pressure, and withdrawing said ram, substantially as described.

4. T e method of packing isinglass which con in forming it into sheets, winding said sheets so coils, compressing said coils laid edgewise into a case ad pted to withsti rd pressure, and closing said case in such manner as to withstand pres ure, substantially as described.

5. The method of packing isinglass which consists in iormi 0 said material into sheets, rolling said sheets to form coils, compressing said coils in a metal case adapted to withstand interior pressure, and closing said case in such ma; nor as to withstand pressure,

tially as described.

d of packing isinglass which in formin said material into sheets, rolling said sheets to form coils, compressing said coils in a case adapted to withstand interior pressure, and l hermetically closing said case in such manner as to vnthstand pressure, substantially as described.

in testimony whereof I aHiX my signature in pr sense of two witnesses.
